Ribbed Floor System
Entrance flooring systems.
Ribbed floor system. Ribbed slabs are made up of wide band beams running between columns with narrow ribs spanning the orthogonal direction. Ribbed or waffle slab is a slab system which consists of series of parallel reinforced concrete t beams framing into reinforced concrete girders. Waffle slabs tend to be deeper than the equivalent ribbed slab. While the isostatic inspiration for the rib patt erns of nervi s floor systems is well.
A well designed entrance flooring system will prevent dirt and moisture from being tracked in and thereby prolonges the life of interior flooring reduces cleaning maintenance costs and the potential for slip injuries. System culminating in n ervi s patented ribbed flo or systems. The historical discussion includes the evolution of the floor slab from a non structural element to an inspired structural system culminating in nervi s patented ribbed floor systems. This form of construction is not very common because of the formwork costs and the low fire rating.
The extended part is known as ribs. The spacing between the ribs should be in general 20 30 inch. Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. Ribbed waffle slab system.
Entrance flooring is fundamental to modern building design. The slab is the flange of the beam and the extended part is the web. Nervi and arcangeli collaborated with architect carlo cestelli guidi for the factory design which required a wide spanning floor system capable of supporting heavy wool spinning machinery 14.
